Transverse aortic constriction (TAC) in the mouse is a commonly used experimental model to study mechanisms underlying cardiac hypertrophy and heart failure development. Here, we describe procedures to constrict the aorta to create a reproducible degree of cardiac hypertrophy in mice.

Minimally invasive transverse aortic constriction (MTAC) conserves the essentials of regular transverse aortic constriction (TAC) while eliminating the use of a ventilator with tracheal intubation. It proves to be a highly desirable method for high-throughput studies on left ventricular overload, particularly in translational studies.

What is a Mode?

The mode is one of the commonly used measures of a central tendency. It is defined as the most frequent value in a data set. There can be more than one mode in a data set if multiple values have the same highest frequency. For instance, suppose that the Statistics exam scores of 20 students are: 50; 53; 59; 59; 63; 63; 72; 72; 72; 72; 72; 76; 78; 81; 83; 84; 84; 84; 90; 93. Here, the mode is 72, as it occurs most frequently, five times. A data set with two modes is called bimodal. For example,...

Speed of a Transverse Wave

The speed of a wave depends on the characteristics of the medium. For example, in the case of a guitar, the strings vibrate to produce the sound. The speed of the waves on the strings and the wavelength determine the frequency of the sound produced. The strings on a guitar have different thicknesses but may be made of similar material. They have different linear densities, and the linear density is defined as the mass per length. One of the key properties of any wave is the wave speed. Light...

FAQs
The system sends ultrasound pulses repeatedly along the selected scan line and assigns each returning echo a depth and time position. As an interface changes location, its displayed trace shifts across successive recordings. This converts movement into a time-dependent pattern, allowing investigators to examine rhythmic or positional changes rather than relying on a single static image.
A transverse orientation places the scan line across structures viewed in that plane, so the recorded motion reflects changes encountered along that specific path. The resulting trace is therefore tied to both the selected anatomical position and the direction of measurement. Careful alignment helps relate changes in the trace to changes in structure size or position.
High temporal resolution captures rapid changes that may be difficult to characterize in a single two-dimensional image. In particular, it supports analysis of rhythmic activity and mechanical function by showing how an interface changes over time. Two-dimensional ultrasound remains useful for spatial context, while the motion recording supplies a more focused time-based assessment.
First, the investigator selects a transverse imaging position and places the scan line through the structure of interest. The system then transmits repeated pulses and records returning echoes according to depth and time. The resulting motion traces are examined for changes in interface position, size, or timing, with the selected location providing the anatomical context.
The trace can support assessment of changes in a structure’s size, position, and motion over time. Because the display preserves timing, investigators can also examine rhythmic changes and relate them to mechanical activity. These measurements are most informative when interpreted alongside the corresponding two-dimensional ultrasound view, which helps identify the structures represented by the traces.
Researchers can apply the technique to moving structures such as the heart, blood vessels, and developing tissues. It is particularly relevant when the study requires precise observation of rhythmic activity, changing dimensions, or mechanical function. Combining the time-resolved recording with conventional two-dimensional ultrasound helps connect quantitative motion patterns to the broader anatomy.
